Trying to discover new/unheard Linux desktop programs (Sorry for the confusion).
Edit: I apologise for confusing a lot of people. I meant Linux desktop “programs” coming from Windows/Mac. I'm used to calling them “apps”.
Edit: 🙌 I’m overwhelmed with the great “programs” people have recommended in the comment section. Thank you guys.
There's no doubt there are a great variety of Linux packages in use.
Recently I did a CD install of Debian 12 (Bookworm) desktop with Gnome, which loads a bunch of stuff over the Net. Here are extra packages that I installed manually. The first set is used by and with an automated configuration script that I wrote, so they have to come in to begin with.
Here are third-party packages I admire. These are not available in Debian repositories although some provide Debian-compatible repositories of their own.
Tor Browser Bundle: Anonymizing Network Browser
This is available from https://dist.torproject.org/torbrowser/ as a tarball. This should be unpacked and the whole tor-browser_en-US directory moved to the ~user folder. This is so that the browser can auto-update at user authority as the need arises.
RetroShare: Secure Communications with Friends
This has its own Debian-compatible repository.
metar: A Package to Parse METAR Coded Weather Reports
weeWX: Open source software for backyard weather stations.
From http://weewx.com/docs/debian.htm. Although a Debian package exists, doing any development practically requires that all the code be in user-space, so don't install the package. Download it instead.
OpenHAB: Home Automation
This has its own Debian-compatible repository.
Ant: GTK3/4 Themes by eliverlara
From https://www.gnome-look.org/browse?cat=135&ord=latest.
This is for claws-mail. It provides better contrast.
